Mixed Crystal Formation

A strategy to continuously tune the exchange constant J and the critical temperature Tc in the 1D coordination polymers [Co(NCS)x(NCSe)2−x(pyridine)2]n is reported. For such mixed crystals, prepared by annealing and from solution, an increase of J and Tc with increasing selenocyanate content is observed.

Mixed Crystal Formation

Mixed crystals of the formulae CaGaAlO4 (1) and CaGa0.5Al1.5O4 (2) were investigated by X-ray single crystal work. 1 shows a tetrahedral orientation like that of CaGa2O4 (monokl.), 2 another one of CaAl2O4. A discussion of the different polyhedral arrangement of the stuffed tridymite structures is given.

The reaction heats for the mixed crystal formation in the LaC2-YC2 system were obtained from the equilibrium gas pressures measured during the carboreduction. The low positive values of the reaction heats are consistent with the X-ray diffraction study of the carbothermal reduction products of the oxides, where the formation of the (La, Y)C2 dicarbide mixed crystals was only observed in the two side regions up to 25 mol.% of each of the minority components. The composition of the gaseous hydrolysis products of the (La, Y)C2 mixed crystals corresponds to the hydrolysis products of the dicarbide. No methane was detected for samples with low yttrium contents.
